I filed an extension and made the estimated payment, but I don't see that payment coming out of my bank account. How can I verify that the cash will clear by tonight?

No worries; as long as you filed your return or extension on or before April 15, 2019 and you selected April 15, 2019 (or earlier) as your payment date, you won't get penalized for late payment.

In the meantime, keep an eye on your bank account — if you still don't see the debit 7–10 days after your return has been accepted, call IRS e-file Payment Services at 1-888-353-4537 or contact your state tax agency, as appropriate.
